I have to agree with Flia in that Jester never appears in the manga. Arkham having demonic powers in the manga is debatable: He knows a lot about demons, and humans can use demonic powers--It happens several times in the Anime as well; so if Arkham does use demonic power in the manga, that doesn't mean he's a demon yet.

We're really handicapped by the lack of the 3rd volume, which was supposed to detail the history of Lady. In DMC3, Dante clearly tells Vergil "At any rate, it has been over a year since we last met." If we assume the manga is canon, then that means the events of the manga could have happened well over a year before the game starts. We can't really pin down a timeline, unfortunately. If you want to list the contradictions you see, might I suggest you make a blog post with them? Or put them on a talk page? That way the community can cross-check them!
